A Philharmonic Menu of Young Composers

American composers 40 and under are the focus of the New York Philharmonic’s latest Contact! new-music concert, on Monday, Nov. 16. The first Contact! to be hosted at the recently opened performance space National Sawdust, in Williamsburg, Brooklyn, the event features chamber works by Kate Soper, Adam Schoenberg, Nathan Heidelberger and Caroline Mallonée. Mario Davidovsky, born in Argentina but a resident of the United States for the past half-century, represents an older generation with his sextet “Flashbacks.” (7:30 p.m., 80 North Sixth Street, 646-779-8455, nationalsawdust.org.)
